Abstract: The present disclosure relates to a cap assembly, a battery including the cap assembly, and a battery pack including the cap assembly. A cap assembly according to one embodiment includes a cap plate coupled to a case to cover an opening in the case, which accommodates an electrode assembly therein, a terminal extending through the cap plate, with a first end portion of is the terminal being electrically connected to an electrode of the electrode assembly and a second end portion of the terminal protruding outside of the case, an insulating member at least a portion of which is disposed between the cap plate and the terminal to electrically insulate the cap plate and the terminal, and a wiring member electrically connecting the cap plate and the terminal.

Abstract: A battery module includes a housing; one or more battery cells arranged in the housing and including a cell terminal; a bus bar holder above the one or more battery cells and including an opening through which the cell terminal is exposed; and a bus bar supported by the bus bar holder, connected to the cell terminal, and including a first surface and a second surface located in a direction opposite to the first surface, and the bus bar holder includes a first support portion that is in contact with the first surface, and a second support portion spaced apart from the first support portion and in contact with the second surface.

Abstract: A battery module includes a battery cell stack including a plurality of battery cells, a plurality of busbars electrically connecting the plurality of battery cells, and a module housing made of a synthetic resin material, and including a busbar holder portion supporting the plurality of busbars, and a sidewall portion surrounding side surfaces of the battery cell stack that does not face the busbar holder portion and connected to the busbar holder portion.

Abstract: Disclosed is a manual service disconnect comprising: an upper housing which has thereinside a plate-shaped upper bus bar terminal; and a lower housing comprising a lower bus bar terminal of which the top is opened so as to be coupled to the upper housing, the lower bus bar terminal having thereinside a first bus bar terminal and a second bus bar terminal which, when being coupled to the upper housing, electrically contact, in the form of a slot, the upper bus bar terminal on the front surface and the rear surface, wherein the first bus bar terminal comprises a first contact part which contacts the upper bus bar terminal and a first plug part extending from the first contact part, and the second bus bar terminal comprises a second contact part which contacts the upper bus bar terminal and a second plug part extending from the second contact part.

Abstract: There is provided a transformer and a method of manufacturing the same. The transformer includes a bobbin wound with coils; cores having center leg parts inserted from both ends of the bobbin and contacting each other; and a shielding member preventing an inflow of an impregnant into the center leg parts inside the bobbin during a varnish impregnation of the cores.

Abstract: There is provided a transformer including cores combined with a bobbin wound with coils, and center leg parts extended from the cores and contacting each other by being inserted into both ends of the bobbin, wherein stress dispersion hole, dispersing stress occurring according to temperature variations around the cores, is formed at the edge of center leg connection parts of the cores from which the center leg parts are extended.
